TO ALL WHOM IT MAY CONCERN:

Be it known that I, Enos H. McAItTnuu, of Hillsdalc, county ofColumbia," and State of New York, have invented a certain newand usefulMachine for Cutting and Folding Paper; and I do hereby declare that thefollowing is a full and exact description thereof.

- The object of my invention is to produce a machincwhich cuts paperfrom the endless .rolls, either singly or by the quire, and'to fold thesame in the middle, which latter operation has been done hitherto, as Ibelieve, by manual labor. My machine performs these operations muchmoreperfectly and faster than can be done by hand. i v

Thenature' of my invention consists,- firstly, in means for feeding the,paper; secondly, in means for cutting the paper by a peculiar and noveldraw-cutting motion; thirdly, in means fol-folding the paper, which isdone by three distinct motions: first,'by placing a sharp or thinfolding-plate on the top of the paper over which the samcis to befolded; second, the motion of the folding-table, folding the paper byits action over the edge of the thin folding-plate; third, in a motionto remove, by the action of the folding-plate, the paper which has beenoperated upon-from the table' fourth inmeansfor regulating the length ofthe paper which is to be out before it is acted upon by the folder.

. To enable others skilled in the art to make and use my invention, Iwill proceed-to describe the same by. the aid of the accompanyingdrawing:

Similar letters of referencee indicate like parts in the differentfigures.

Figure 1 is a side elevation, parts of the frame ofthe machine beingremoved to allow the working of the mechanism better to be seen. i

' Figure 2 is an end elevation, with parts of the end frame likewiseremoved, to show the working parts more clearly.

I will now proceed to describe thcimeans by which the differentoperations are performed in the order given above. I

First. The feeding apparatus consists of two rollers, B B, resting inbearings b b of the framing A of the maching. The roller B has mountedonthe end of its shaft a pinion, B to which is given an intermittentmotion, necessary for feeding the paper-roller. B is the feed-rollerproper, the roller B being only a counter-roller, producing thenecessary friction to draw the paper through- The intermittent motionisprodu'ced by a gear segment, {3, mounted onthe shaft 0, and gearinginto the pinion B of large roller B. The amount of feed is regulated bythe length or number of teeth in this segment C, by whichthc amount of'turn of rollerB is governed. Shaft c has on its other end a gear-whee],G ,'which is acted upon by a gear-wheel, D, on the main driving-shaft Dof the machine, through an intermediate gear, 0 Thcmotiqn of thegear-whecl D, as well as that of the gear segment 0, is intermittent,and I will proceed to describe the means bywhich said intermittentmotion is produced. Gear-wheel D is loose on the main shaft D; it iscoupled to-the shaft by a clutch, d. This latter engages and disengagesl) by the following mechanism: E is a small pinion, gearing into agearwheel, E, secured by a stud to frame A. In front of this lattergear-wheel E, is placed al'horizontal slide-rod, E'fl'g ided in thebearings a a, and having-two studs e e, secured to it, which pass inwardradially towards the centre of E, in the manner embracing the two sidesof E like a fork. On the two opposite faces of E are circular cams e" ewhich act successively, substantially as shown in the drawing, on thetwo studs 6 and c, which are placed apart the breadth of the wheel andthe amount of throw of one of the cams, and in this manner give to thebar or slide-rod, E, a to-and-fro motion. An arm, E reaches down from Eand encircles the groove in clutch d- The clutch takes part in thismanner of the to-and-fro motion of the'sliding-bar E and places in orout of gear a gear-wheel, D, which intermittent motion is transmittedto'the feed-roller B by the means above described.

When quires are tobe folded the feeding must take place as often asnecessary to make up the quire to one of the folding motions, and thepaper being drawn from four, five, or more endless rolls, it isnecessary to take correspondingly many feeds and cuts to make upthequire before the action of folding takes place.

After each feed the cutting of the paper must be done, which constitutesthe second operation. On the same shaft 0, on which is mounted thesegmental gear-wheel C, is mounted on the opposite side anothersegmental ss,45o 2 gearewheel, F. The teeth of this latter are soarranged as to begin to act as soon as the feed motion is stopped, thatis, as soon as the segment G stops to act on pinion B. This gear segmentP acts on a pinion, F, on the shaftf. The pinion Fhas on its innersurface a stud,f, which gives an up-and-down motion to a cam frame, fand rodf This latter takes hold on one of the arms of an angle-lever,the arms of which I will callf and f and which turns on ccntref. It isreadily understood that when arm f is moved upward by thestud f and camframe f, the end of arm f will describe an arc of a circle from centref, and is at the same time lowered. This latter arm is fastened to theknife G by a small bolt, '9. The knife is guided on the frame inbearings a a. This knife is well sharpened, and passes along the edge ofa stationary knife-blade, G, secured to frame A of the machine. Theother endof the knife G has a slanting slot, 9, surrounding a stationarypin, fixed to the guide-bearing of the knife, and the whole arranged insuch a manner that when the knife is pulled towards the left, itwilhbe'movcd sidewise, and at the same time be depressed so as to passby the edge of the stationary knife-blade G, and cut the paper or anyother material interposed.

The motion produced by these mechanical means is the one best adaptedfor cutting, and is known under the name of draw shearing out.

After the paper is cut it falls on the folding-table ready to be folded,which constitutes the third or folding operation. The paper coming fromthe feed-rollers B B, is guided on top of the folding-table. The tableis formed of two halves, H H, the latter being stationary, and theformer movable and folding ov er H, by means of the hinge which connectsthe two halves at the point It. Before this movement takes place, thethin folding-plate L places itself on the top of the paper to be folded;it reaches fromth'ebaok of the stationary part H of the folding-table tothe joint It, where the part H connects to H The paper is therefore heldfirmly at the pointwhere the fold is to be made.

The means by which the motion of this operation takes place are asfollows The motion must be an intermitten t one, acting at' the timewhen the feed-rollers and the knife are at a stand-still: -The clutchdon the main shaft is a double one,- engaging in a clutch on abevel-wheel, J, loose on shaft D. p This is done by the same g'neansthat the clutch engages and disengages the gear D of the feed motion.When D is disengaged, the teeth on the opposite end of the double clutchd engage in the teeth on bevel-gear J. By the motion of the latter thefolding operation is performed. This motion of J is transmitted bybevel-gear J, shaft j, by bevel-gear J and J to a shaft, K.- From thisshaft the folding part H of the folding-table is operated. On each endof shaft K is placed a pitman-Whcel, K K, with crimk-pins la Ir. On Hare secured two lever-arms, h 71., formed, for the sake of stability, ofthe shape of an arc of a circle. The points-h h of these lever-arms areconnected to the crank-pins k k", by the two rods K K. The amount ofmotion of crank-pins 7c and k is such as to turn the folding par't H,swinging on the point it to an angle of one hundred and eighty degrees,or from its original horizontal position to the horizontal position overthe stationary part H, thereby folding the paper placed on the same.Before this action of H takes place, the thinfolding-plate L, over whichthe paper is folded, is placed on the paper. This is done by thefollowing means: On shaft k, b'et\vecn the pitman-wheels,

is a pinion, I, geared into a wheel, M, of double the size, on a shaft,or. From here the motion is transmitted. by bevel-gears N O, shaft 0,bevel-gear O and to shaft 1;. On is a cam-wheel Q, the cam part q ofwhich acts on a tappct, L, on awhcel, -L', on a shaft, Z, giving thislatter a partial turn. On this shaft Z is secured the folding-plate L,which is operated by these means Wheel L has a groove worked out on itscircumference; over it passes a cord, down to spring L; the action ofthis latter brings folding-plate L over the paper in the position shownintlie drawings. -When L is brought to an upright position by the meanshereinbefore described,

it will carry along with it the paper folded over its edge, which cannow be readily removed by hand. 'L

remains'for a certain time, necessary for feeding and cutting, in thatposition.

To fold paper of less width, (accepting the machine now to fold thelargest everunccessary,) the frame part A, carrying the feeding-table,can be shortened by bringing the joint 72 of the folding part II nearerto the.

cutting-knife G, to the amount to which the breadth of the folded sheetsis to be reduced, and moving in the gauge L, to the same distanceagainst which the paper is fed. The food must be changed in the mannerhereinbefore described. To allowthe shifting of the frame A, the latteris secured to A by four bolts, R R BF'R; the frame A is slotted, inwhich slot the bolts R pass. To make a change the bolts R 11, etc, areloosened, the frame A set,- tlic bolts R R, etc., tightened again, andthe machine is ready to operate. The plate H, reaching up closcto theknife, must be shortened, for this purpose it is formed at the end ofslats or narrow strips .of wood, secured to the main body of H by bolts.According to the change in width, more or less slats are taken from thetable H.

The operation is now as follows: First, the feed takes place, bringingthe paper on the folding-table up to gauge L. The feed being arrested,the cutting takes place. This being done, the motion is transferred tothe folding apparatus, which has remained at rest during the firstoperation. The cam q releases the tappct L on shaft 1, and thefolding-plate comes down on the top of the paper to be operated upon,and holds the same.

Now the folding part H isworked and the fold is produced over the edgeof the folding-plate L. The part H now moves back to its originalhorizontal position. The cam part q now acts ag'ain'on tappet L, and Lis brought .toa vertical or nearly vertical position, bringing alongwith it the paper folded. Here the motion to the folding mechanism isended; the motion of the feeding and cutting mechanism begins anew.During this latter time the folded paper is removed from L, and so on.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent is as follows! I 1. I claim the applicationof a folding apparatus to a paper-cutting machine, substantially as andfor the purposes herein set forth.

2. I claim the movable part H of a folding-table, in combination withthe stationary part II of the same, and the folding-plate L, operatingsubstantially as and for the purposes herein set forth.

3. I claim, in combination with a folding machine, thc folding-plate L,substantially as and for the purpose herein specified.

4. I claim, in a folding apparatus, the folding-plate L, in combinationwith tappet L, cam-wheel Q, spring L operating substantially as and forthe purpose herein set forth. i

5. I claim, in paper-cutters, the knife G, in combination withangle-levers ff slot g, and pin, operating substantially and for thepurpose herein set forth.

6. I.clain1 the provisions for adjusting the folding-table to thedifferent widths of paper to be folded, substantially as aind for thepurpose herein specified.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
